A charming and practical garage apartment offering 429 heated sq. ft., traditional detailing, and flexible living space—perfect for ADUs, guest suites, or rental income.

This Carriage House garage apartment combines simplicity, efficiency, and classic design appeal. With its timeless gable-front silhouette, clean white siding, black garage door, and upper-level dormer window, this structure fits seamlessly into suburban neighborhoods, rural properties, or back-lot accessory dwelling configurations. Designed to maximize vertical space and minimize footprint, this plan offers exceptional versatility for homeowners seeking extra living space without committing to a full-scale home addition.

Exterior Design & Architectural Character

The exterior features crisp horizontal siding paired with subtle brick accents at the foundation—an attractive and durable combination that enhances curb appeal. The black two-car garage door provides strong visual contrast, while the centered upper dormer window introduces symmetry, natural lighting, and a cozy architectural focal point. The steep gable roof aligns with classic American Carriage House tradition, offering both practicality and aesthetic charm.

This balance of simplicity and refinement makes the structure suitable for multiple uses—from home workshops and vehicle storage to upper-level living quarters ideal for tenants, extended family, or working professionals. The proportions, materials, and layout all contribute to a polished and purposeful design.

Upper-Level Living Space

The heated living area totals 429 sq. ft., with every square foot intentionally designed to add value and functionality. The upper-level layout includes:

• 1 private bedroom with space-efficient flow and room for a full or queen bed.
• 1 full bathroom positioned for quiet and convenience.
• Open living area ideal for lounging, working, or casual dining.
• Natural light entering through the dormer window, enhancing the airy feel.

This compact space works beautifully as a long-term rental, a short-term Airbnb, a dedicated guest suite, or a private living area for older children or relatives. Its footprint and layout make it extremely cost-efficient to heat, cool, maintain, and furnish.

Garage & Storage Features

The ground-level two-car garage provides 612 sq. ft. of unheated space, perfectly suited for:

• Vehicle storage
• Hobby or workshop setup
• Seasonal storage
• Recreational gear, tools, and equipment

The extra width and straightforward layout support a variety of needs, while the slab foundation keeps construction costs manageable. The clean roofline and minimal overhangs provide practical weather protection and lower long-term maintenance.
